Is there a proper technique to perform a fingerstick glucose test?

Not really: Hi. It's so easy, it's like falling outta bed! Hands should be clean, but unless you have a dirty job, no one washes just for testing if your hands are reasonably clean. Don't dip your fingers in honey over the test site; glucose on the skin would, of course, influence results. Otherwise, no special routine. No one uses alcohol pads (like they do at doctors offices, etc). It's SO easy! Good luck! ...Read more

Is there a device that doesn't have to be calibrated after a finger meter test?

Is there a device that doesn't have to be calibrated after a finger meter test?

Yes please reed?: 'no coding' systems. Older systems required 'coding' of the strips to the meter. This carried a risk of 'miscoding', which can lead to inaccurate results. Two approaches have resulted in systems that no longer require coding. Some systems are 'autocoded', where technology is used to code each strip to the meter. And some are manufactured to a 'single code', thereby avoiding the risk of miscoding. ...Read more
